I have a 2008R2 Windows server and it has 10.10.10.8 and 10.10.80.8 bound to the NIC. We had an issue where both IP addresses were registering in DNS. We found that if we applied a hot fix and ran a command, (Netsh int ipv4 add address NIC1 10.10.80.8 skipassource=true), and then deleted the 10.10.80.8 address out of DNS that it would fix our issue, and it did.
My question is this. If we changed the IP address to 10.10.80.10, for example, does that break our solution and allow the 10.10.80.x address to show up in DNS again?
